Mobile communication system, home base station, and mobile station

Abstract

In a mobile communication system according to the present invention, the mobile communication system is configured to manage a specific mobile station which is allowed to communicate through a CSG cell under the control of a home base station (Home-eNB); and a general mobile station (UE) other than the specific mobile station is configured to be capable of using the CSG cell as a camped cell, only when broadcast information indicating an allowance of a camping in the specific cell is received.

The invention claimed is: 
     
       1. A mobile communication system, wherein
 the mobile communication system is configured to manage a specific mobile station which is allowed to communicate through a specific cell; 
 a general mobile station is configured to be capable of using a general cell as a camped cell, the general cell being a cell which excludes a Closed Subscriber Group (CSG) cell; 
 the general mobile station other than the specific mobile station is configured to be capable of using the specific cell as a camped cell, when a first broadcast information indicating an allowance of a camping in the specific cell is received; 
 the general mobile station using the specific cell as a camped cell is configured to transmit a connection request to the specific cell and configured to be capable of communicating through the specific cell, as long as broadcast information indicating a prohibition of a communication through the specific cell is not received; 
 the specific cell is the Closed Subscriber Group (CSG) cell, the specific mobile station belongs to the CSG, and the general mobile station does not belong to the CSG before the general mobile station receives the first broadcast information, and 
 a charge of a communication performed by the specific mobile station through the specific cell is configured to be differentiated from a charge of a communication performed by the general mobile station through the specific cell. 
 
     
     
       2. The mobile communication system according to  claim 1 , wherein a reception control method for a mobile originating call request transmitted by the specific mobile station to the specific cell is configured to be differentiated from a reception control method for a mobile originating call request transmitted by the general mobile station to the specific cell. 
     
     
       3. The mobile communication system according to  claim 1 , wherein a transmission probability or a restriction probability of a mobile originating call request for the specific cell by the specific mobile station is configured to be differentiated from a transmission probability or a restriction probability of a mobile originating call request for the specific cell by the general mobile station. 
     
     
       4. The mobile communication system according to  claim 1 , wherein a type of communication service providable to the specific mobile station through the specific cell is configured to be differentiated from a type of communication service providable to the general mobile station through the specific cell. 
     
     
       5. The mobile communication system according to  claim 1 , wherein a data transmission rate in an uplink communication performed by the specific mobile station through the specific cell is configured to be differentiated from a data transmission rate in an uplink communication performed by the general mobile station through the specific cell. 
     
     
       6. The mobile communication system according to  claim 1 , wherein a service quality of a communication performed by the specific mobile station through the specific cell is configured to be differentiated from a service quality of a communication performed by the general mobile station through the specific cell. 
     
     
       7. A mobile station which is used in a mobile communication system configured to manage a specific mobile station which is allowed to communicating through a specific cell, the mobile station comprising:
 a camped cell determination section configured to be capable of using the specific cell as a camped cell, when the mobile station is not managed as the specific mobile station, and when a first broadcast information indicating an allowance of a camping in the specific cell is received; 
 the camped cell determination section is configured to be capable of using a general cell as a camped cell, the general cell being a cell which excludes a Closed Subscriber Group (CSG) cell; 
 a mobile originating call processor section configured to be capable of transmitting a connection request to the specific cell, when the specific cell is used as a camped cell, unless the broadcast information indicating a prohibition of a communication through the specific cell is received, 
 wherein the specific cell is the Closed Subscriber Group (CSG) cell, the specific mobile station belongs to the CSG, and the general mobile station does not belong to the CSG before the general mobile station receives the first broadcast information, and 
 wherein a charge of a communication performed by the specific mobile station though the specific cell is configured to be differentiated from a charge of a communication performed by the general mobile station through the specific cell.
